Application fi1ed December 29, 1919.

19, Switzerland, haveinvented certain new and useful Improvements inMeans foriRecooling Water for the Condensatlon of Steam on Vehicles; andI do hereby declare the.

following to be a clear, full, and exact description of thepinvention,such as will enable others skilled in the art to which it-appertains tomake anduse 'the same, reference being had to the accompanying drawing,and to letters: or figures of reference marked thereon, which form apart: of this specifi+ cationsv in the main in the direction of runningand in itsfron-t part openi to the front as well asto the vsides; Thearrangement ismade such, that =ion encounteringa high side-wind, thatpart of the entrance" opening-which is,

at the lee sid'e, may. be; at 1 least partly shut. The coa'l 'bunkernecessary: for the working of the vehicle with steam may be builtwedge-shaped and co-axially in the front part of the airchannel.

The special advantages may be explained when entering on the details ofthe exemplification of this invention diagrammatically shown on thedrawing, on which Figure 1 is a vertical longitudinal section,

Fig. 2 represents a plan of a steam-locos motive tender which is movingin the direction of arrow P. On the frame 1 of the tender, provided withthree axles, the water re-cooling device and the coal-bunker arearranged. The re-cooling device consists in the main of an air-channel ar-72 and of a guiding-device for the water. The'aii channel is ofrectangular section in the rear third of its length that isapproximately from line I-II of Fig. 2 up to the dischargesectionA-BC-D. Into the entrance of the air-channel the coal-bunker is builtin, which is chiefly of a triangular-like shape E-FG in the verticallongitudinal sec-. tion (Fig. 1) and of a triangular-like shape H-JK inthe horizontal section (Fig. 2). As may be seen in Fig. 2 thecoal-bunker provides space between its outer wall and Specification ofLetters Patent.

The cooled 3 water si collected at the bottom of reservoir 5 and is thereupon conducted backby means the tender isgenerated which issue's again'at the side II thusflowing not at all'o'r onlytoa small degree along' the channel and whichI does not exert the'water;

of the section H-J-K is not provided and therefore the possibilityexists that the sidewind passes without restriction from the part L-M ofthe opening. on-side I directly to the part N--() of the opening. onside II transversely throughthe whole tender. In order to prevent this;the sidelparts L-M and N-O of the entrance opening may for p anycooling-effect; on; "This -1s espe'cia'lly the 1 case, if, as may beseen in Fig. 2, the coal-bunker example be provided with pivoted or rotatable narrow vertically arranged strips of sheet metal or shutters 7 and8 respectively. If the wind blows from the direction of side I, thesheet-metal strips 8 are turned toward the direction of running by meansof alever apparatus not shown in'the drawing, whereby'the part N-O is,closed and the air required for cooling the water enters the channelfrom the left side only,

that is through the front part I-I-L and the side part L-M as well asthrough the front which is left open 7 N-K'on the right side to a smallextent.

I claim:

1. In a device for re-cooling water for the condensation of steam onvehicles, an airchannel, the axis of which is in the main arranged inthe directlon of running where- 'by the speed of the vehicle producesthe necessary air-current, means to cause the water to be re-cooled topass transversely through the channel and means arranged in the forepart of the air channel to provide for the entrance of the air from thefront and from the sides when working normally.

2. In a device for re-cooling water for the condensation of steam onvehicles, an airchannel, the axis of which is in the main arranged inthe direction of running where-. by the speed of the vehicle producesthe necessary aircurrent, means to cause the water to be re-cooled topass transversely through the channel and means arranged in I the forepartvof the air channel to provide for the entrance of the air from thefront and from the sides, the latter means being provided with-a devicefor adjusting the sectional area of the entrance. r

8. Ina device for l e-cooling water for the condensation of steam onvehicles, an air channel the axis; of which is in the main arranged inthe direction of running wherebyithe speed of the vehicle produces thenecessary air-current, means to cause the condensation of steam onvehicles, an airchannel, the axis of which is in the main my inventionarranged in the direction of running where by the speed of the vehicleproduces the necessary air-current, means to cause the water to bere-cooled to pass transversely through the channel, means adapted toprovide for the entrance of the air from the front and from the sides,the front part of the air channel being arranged to provide awedge-shaped channel hollow space to be used as a coal-bunker.

5. In a device for re-cooling water for, the condensation of steam onvehicles, an air channel the axis of'which is inthe main horizontal,means to cause the waterto be re-cooled to pass transversely throughsaid channel, openings at the front end of said channel to admit airthereto,'and ashutter to control the admission.

6. In a device for re-coolingwater for the condensation of steam onvehicles, an air channel the axis of which is mainly horizontal, meansto cause the water to be re-cooled to pass transversely through saidchannel,

' said channel having front air entranceopenings and sideair entranceopen1ngs,shutters controlling the side openings, and a coal bunkerincluded in the side and front openings.

7. condensation of steam on vehicles, an air channel the axis of whichis mainly horizontal, said channel having a substantiall horizontalinlet and exit at its ends, an front air inlets and lateral air inlets,and a coal bunker included between said lateral inlets and said frontinlets.
